Used primarily as a fluorinating agent in organic synthesis, enabling the replacement of hydrogen or other functional groups with fluorine atoms. This is valuable in the development of pharmaceuticals, agrochemicals, and specialty materials where fluorinated compounds exhibit enhanced stability, bioavailability, or reactivity. Also employed in the preparation of other metal fluorides and in research for its strong oxidizing properties under controlled conditions. Its high reactivity makes it suitable for converting hydrocarbons into perfluorinated derivatives, useful in creating heat-resistant and chemically inert materials.
